IMPROVEMENT IN CARTRIDGES.

Specification forming part of Letters Patent No. l 12,305, datedFebruary 28, 1871.

To all whom it may concern Be it known that I, RoLLrN WHITE, of Lowell,inthe county of Middlesex, and in the State of Massachusetts, haveinvented certain new and useful Improvements in Cartridges;

' and do hereby declare that the following is a full, clear, and exactdescription thereof, reference being had to the accompanying drawing,and 'to the letters of reference marked thereon, making a part of thisspecification.

The nature of my invention consists, rst, in a cap made of one or morepieces, carrying its own anvil, and provided around its exterior surfacewith one or more tongues or grooves 5 and, second, in combination withsuch a cap, of a cartridge-base having an aperture for the insertion ofsaid cap, said aperture being provided with one or more grooves ortongues corresponding with the tongues or grooves of the cap..

In order to enable others skilled in the art to which my inventionappertains to make and use the same, I will now proceed to describe itsconstruction and operation, referring to the annexed drawing, whichrepresents various forms of cap, all having the grooves or tongues.

A represents a cap made of one or more pieces and provided withfulminate-receptacle a and anvil b.

Figures l and 2 show a cap with its anvil -Inade of one piece and avent, i, through the anvil 5 Fig. 4 shows, also, a cap made of one piecewith its anvil, butwithno vent 5 while Fig. 3 shows the anvil formed ofa separate piece of metal from the cap and two vents through the anvil.

Around the exterior surface of the cap A is formed one or more grooves,d, or tongues e.

B represents the base of the cartridge-shell, having an aperture intowhich the cap is to be inserted, and said aperture is provided witheither one or more tongues or one or more grooves, to correspond withthe grooves or tongues on the exterior surfaceof the cap.

The caps A may be of any desired form, either cylindrical, conical, orany other suitable shape, and may have one or more grooves or tongues,as may be necessary, or according to the apertures made to receive oriit into it.

They may be corrugated, concave, convex, or

flat, and either bent, forced, or pressed into the aperture, and made astight as desirable, thus forming, as it were, one piece with the base ofthe cartridge-shell B.

The caps are manufactured and filled withl greater convenience separatefrom the cartridge, and when fastened in as above described they may besaid to form a part of the shells.

The cap represented in Fig, 4 has a tongue or flange, f,which, when thecap is inserted into the aperture of the cartridge-shell, is to bepressed down so as to it over the tongue on the inside of the aperture,and thus hold the cap flrmly in its place. This cap may also have avent, the same as the others represented in the drawing.

Having thus fully described .my invention, what I claim as new, anddesire to secure by Letters Patent, is-

The combination of the cartridge-case and cap herein described, oneprovided with an annular tongue and the other with a groove, allsubstantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand this17th day of January, 1871.

ROLLIN WHITE.
